[0055] To address the technical problem of low resource utilization in existing underwater acoustic channels, this application provides an underwater acoustic channel resource updating device that can improve the utilization rate of underwater acoustic channel resources.

[0056] Figure 1 This is a flowchart illustrating a method for updating underwater acoustic channel resources according to an embodiment of this application. In one embodiment, the method includes:

[0057] S1. Obtain the initial underwater acoustic channel resources of the target user node.

[0058] Initial underwater acoustic channel resources include initial bandwidth. Initial bandwidth refers to the initial bandwidth resources allocated by the base station to the target user node. The target user node can be an underwater observation node. Underwater observation nodes include both fixed underwater nodes and mobile underwater nodes.

[0059] S2. Obtain the channel quality information and service information of the target user node.

[0060] Channel quality information includes channel quality indication, signal-to-interference-plus-noise ratio (SNR), and bit error rate (BER). Service information includes service priority and service traffic requirements. Service priority indicates the importance of the service. Service traffic requirements indicate the bandwidth required for the service.

[0061] Specifically, the target user node sends its channel quality indication, signal-to-interference-plus-noise ratio, bit error rate, service priority, and service traffic requirements to the base station.

[0062] S3. Determine the first bandwidth of the target user node based on channel quality information and service information.

[0063] It should be noted that the following embodiments of this application will describe in detail how to determine the first bandwidth of the target user node based on channel quality information and service information. This will not be repeated here.

[0064] S4. Update the initial bandwidth based on the first bandwidth.

[0065] In this embodiment, the obtained first bandwidth is used to update the initial bandwidth of the target user node, so that the target user node uses the updated initial bandwidth for data transmission.

[0066] It should be noted that the base station periodically executes S1-S4 to dynamically adjust the underwater acoustic channel resources of the target user node.

[0067] This application provides a method for updating underwater acoustic channel resources. The method includes: acquiring initial underwater acoustic channel resources of a target user node, the initial underwater acoustic channel resources including initial bandwidth; acquiring channel quality information and service information of the target user node; determining a first bandwidth of the target user node based on the channel quality information and the service information; and updating the initial bandwidth based on the first bandwidth. In this technical solution, the channel quality information and service information of the target user node are acquired, and the first bandwidth of the target user node is determined based on the channel quality information and service information. Then, the initial bandwidth in the initial underwater acoustic channel resources of the target user node is updated based on the first bandwidth of the target user node. Therefore, the initial bandwidth in the initial underwater acoustic channel resources is not fixed. The initial bandwidth in the initial underwater acoustic channel resources is dynamically adjusted as the channel quality information and service information of the target user node change, effectively improving the utilization rate of underwater acoustic channel resources.

[0068] In one embodiment, the service information includes: service priority and service traffic requirements, and determining the first bandwidth of the target user node based on the channel quality information and the service information includes:

[0069] S31. Determine whether the business priority is greater than the first preset threshold; if yes, execute S32-S34; if no, execute S35.

[0070] This application embodiment uses a fixed numerical range to measure service priority. Specifically, a numerical range of [0, 10] can be used to measure service priority. The higher the number, the more important the corresponding service priority. The first preset threshold can be a value in [0, 10], preferably 5. It should be noted that this application embodiment can also use other methods to measure service priority. This application does not impose any restrictions on this.

[0071] S32. Determine the second bandwidth based on business traffic requirements.

[0072] The second bandwidth is the minimum bandwidth required by the target user node to transmit the service traffic, as determined by the service traffic requirements in this embodiment of the application.

[0073] S33. Determine the third bandwidth based on channel quality information.

[0074] In one embodiment, the channel quality information includes: channel quality indication, signal-to-interference-plus-noise ratio, and bit error rate; determining the third bandwidth based on the channel quality information includes:

[0075] S331. Calculate the channel quality score based on the channel quality indicator, signal-to-interference-plus-noise ratio, and bit error rate.

[0076] Channel quality score (CBS) is used to evaluate the channel quality of a target user node. CBS is typically quantized as an integer level [0, 15]. A higher CBS indicates better channel quality. Signal-to-interference-plus-noise ratio (SNR) is the ratio of received signal power to interference-plus-noise power. A higher SNR indicates better channel quality.

[0077] Specifically, in this embodiment, different weight ratios are set for the channel quality indicator, signal-to-interference-plus-noise ratio (SNR), and bit error rate (BER). Next, the weight values ​​for the channel quality indicator, SNR, and BER are calculated respectively. Finally, the BER weight value is subtracted from the sum of the channel quality indicator's weight value and the SNR's weight value to obtain the final channel quality score. A higher channel quality score indicates better channel quality.

[0078] S332. Determine the third bandwidth based on the channel quality score.

[0079] According to the embodiments of this application, the channel quality score is divided into multiple levels based on experimental data, and each level corresponds to an optimal bandwidth value.

[0080] S34. Determine the first bandwidth based on the second bandwidth and the third bandwidth.

[0081] In one embodiment, determining the first bandwidth based on the second bandwidth and the third bandwidth includes:

[0082] S341. Determine whether the second bandwidth is greater than the third bandwidth; if yes, execute S342; otherwise, execute S342.

[0083] S342, Use the third bandwidth as the first bandwidth.

[0084] When the channel quality of the target user node cannot meet the service traffic requirements, the channel bandwidth of the target user node is adjusted to the third bandwidth to avoid congestion in the underwater acoustic channel of the target user node.

[0085] S343, Use the second bandwidth as the first bandwidth.

[0086] When the channel quality of the target user node can meet the service traffic requirements, the channel bandwidth of the target user node is adjusted to the second bandwidth to accelerate the transmission efficiency of service traffic.

[0087] S35. Keep the first bandwidth unchanged.

[0088] If the target user node has a low priority, there is no need to adjust the underwater channel resources of the target user node.

[0089] In one embodiment, the initial underwater acoustic channel resources further include an initial transmit power, and the method further includes:

[0090] S5. Determine the first transmit power based on service priority.

[0091] It should be noted that the above embodiments of this application have already described in detail how to classify service priorities. Therefore, this application will not repeat that description here. The embodiments of this application determine the transmission power according to different levels of service priorities. The transmission power corresponding to the service priority of the target user node is selected.

[0092] It should be noted that the initial transmit power is the power of the initial transmitted signal of the target user node.

[0093] S6. Update the initial transmission power based on the first transmission power.

[0094] The initial transmission power is directly replaced with the first transmission power.

[0095] In yet another embodiment, before updating the initial transmit power according to the first transmit power, the method further includes:

[0096] S7. Determine the second transmit power based on the channel quality score;

[0097] In this embodiment, the channel quality score is divided into different levels, and each level corresponds to an optimal transmit power. The second transmit power is determined based on the level corresponding to the channel quality score of the target user node.

[0098] The step of updating the initial transmission power based on the first transmission power includes:

[0099] S61. Determine the third transmission power according to the first preset weight ratio, based on the first transmission power and the second transmission power.

[0100] The first preset weighting ratio was obtained by the applicant based on practical experience. Preferably, the first preset weighting ratio is 4:6. Of course, the first preset weighting ratio can be other positive numbers. This application does not impose any restrictions here. It should be noted that the third transmission power is equal to the sum of the weight values ​​of the first transmission power and the second transmission power.

[0101] S62. Update the initial transmission power based on the third transmission power.

[0102] The initial transmission power can be replaced directly with the third transmission power.

[0103] In one embodiment, before updating the initial transmit power according to the third transmit power, the method further includes:

[0104] S8. Determine the fourth transmit power based on the service traffic requirements.

[0105] This application embodiment divides service traffic demand into different traffic ranges based on practical experience, with each traffic range corresponding to an optimal transmission power. This application embodiment determines the fourth transmission power based on the traffic range corresponding to the service traffic demand of the target user node.

[0106] The step of updating the initial transmission power based on the third transmission power includes:

[0107] S621. Determine the fifth transmission power based on the third and fourth transmission powers according to the second preset weight ratio.

[0108] The second preset weighting ratio was obtained by the applicant based on practical experience. Preferably, the second preset weighting ratio can be 3:7. Of course, the second preset weighting ratio can be other positive numbers. This application does not impose any restrictions here.

[0109] It should be noted that S621 is the same as or similar to S61. This application will not elaborate further on this.

[0110] S622. Update the initial transmission power based on the fifth transmission power.

[0111] The initial transmission power can be replaced directly with the fifth transmission power.

[0112] In one embodiment, the initial underwater acoustic channel resource further includes an initial frequency point, and the method further includes:

[0113] S9. Determine the target frequency band based on the channel quality score.

[0114] The target frequency band can be either a high-frequency band or a low-frequency band. In this embodiment, the channel quality score is divided into two intervals, each corresponding to a frequency band. The interval with the higher score corresponds to the high-frequency band, and the interval with the lower score corresponds to the low-frequency band.

[0115] It should be noted that the initial frequency is used for the target user node to send data on the initial frequency.

[0116] S10. Obtain network load information of the base station.

[0117] The network load information refers to the network load information on the base station side.

[0118] S11. Determine the target frequency point from the target frequency band based on the network load information.

[0119] Specifically, the base station determines the congestion status of each user node on the base station side based on network load information. It then selects a relatively idle frequency point from the target frequency band as the target frequency point.

[0120] S12. Update the initial frequency point according to the target frequency point.

[0121] The initial frequency is updated according to the target frequency so that the target user node can transmit data on the updated initial frequency, effectively avoiding congestion in the underwater acoustic communication network.
